tion of the drum 15 determines the length of ing the body of the vehicle, are compressed;

the two parts of the support of the spring on the axle and the frame oi the vehicle are then W'hen this occurs, the springs 1.1 or 19, as the case may be, will return to their normalposition and the band or belt 10 slips freely around the surface of the drum. Un the immediate rebound or opening of the springs 2 of the vehicle, the band and its spring, secured thereto, will cause a braking action on the drums, prethe vehicle-bo in other words, the Jfriction of the belt on the drum surface as the vehicle springs return to their normal position, prevents the quick rebound and throwing up of the body of the car, which is so objectionable to its passengers and fatal in many instances to the springs. lt is obvious that the device does not interfere with the easyaction of the vehicle-springs in compressing, but prevents the reaction or rebound of the same.

Should for any reason it be desired to increase or decrease the braking action. of the belt, then it is necessary to wra more or less of the length of the band orbe t around the `drum surfaces. To attain this object in the device, shown in Fig. 1 of the drawings, the screw 7 is loosened and the base plate 5 is swung around its pivot 6 in one or the other direction, whereby more or less of the band 1() will be in contact with the drums 3 and 4, thus the braking action will be increased or decreased..

In the device shown in Fig; 2, the drum 15 regulates the braking action of the belt. In placing the drum near to the u per end 16 of the slot 16, the length of the Eand in con` tact with the drum surface is decreased, while in placing the drum near to the lower end 16 of the slot the length is increased.

What l claim is:

v1. The combination with a springesupportedvehicle body and its running gear, of a plurality of drums carried by lone of said members, a band passing over` the cylindrical surfaces of saidums and secured to the other of said members and adapted to slide freely on said drums when the springs of said vehicle are compressing and cause a braking action upon said drums on the rebound of said springs, and means for varying the position oi said drums on their sup )ort so as to adjust the braking action of said band.

2. The combination with a spring-supportsowie? ed vehicle body and its ruiming gear," of a plurality of drums carried by one oi' said members, a band passing over said drums and connected to ono of said members, a resilient means secured to lsaid band and connected to the other of said members, and means for varying the positions of said drums on their support so as to vary the length of the band passing `over the saine.

3. 'l he combination with a springsiipported vehicle body and its running gear, of plurality of drums carried by one of said members, a band passinover said drums and connected to one ci? said members, a spring secured to said band and connected. to t e other of said members, and means for varying the positions oi said drums on their `support so as to vary the length of the band passing over the same.

et. 'l ie combination with a springsupported vehicle body and its ruiming gear, oi a plurality of drums carried by one oisaidmembers, a band assing over the cylindrical surfaces of said ruins and secured to the other of said members and adapted 'to siidc freely on said drums when the 'springs of said Vehicle are compressing and cause a braking action upon said drums on the rebound of said s rin s and means ada' ted to chancel the relative position of saidv drums for adjusting the braking action of'said band.
